Irrigation Season to End October 4


The City of Nampa will shut down its irrigation system for the season Wednesday, October 4 to coincide with Pioneer Irrigation District.

As the irrigation districts near the end of their allotment, each district determines when they will shut off the water to customers, which includes the City of Nampa. The City of Nampa receives water from three irrigation districts (Pioneer Irrigation District, Nampa & Meridian Irrigation District and Boise-Kuna Irrigation District). While Nampa & Meridian Irrigation District and Boise-Kuna Irrigation District is tentatively scheduled to end its season October 10, the City of Nampa needs water delivery from all three irrigation districts to fully run our pressurized system.  

Yearly irrigation assessments are calculated and based on the square footage of a property. The irrigation water is not metered, and the length of the season is dependent on the availability of water. 


  • Do not use potable (house) water to irrigate lawns as it will increase the water and sewer charges on your utility bill. The City of Nampa does not have enough back up domestic water to fulfill irrigation needs. 
  • The Nampa Waterworks Division reminds individuals and companies that the city valve should not be turned off when blowing out sprinkler lines. The keyed turnoff is for city emergency use only.

For more information, visit or call (208) 468-5860.
